of pulleys which are adapted to be mounted directly upon a shaft or equivalent part or upon suitable bushings interposed between Athe shaft and the pulley-hub.

The object is to produce a simple, durable, and effective pulley for the purposes for which such devices are employed.

To this end my invention consists in the novel construction, arrangement, and combination ofparts herein shown and described, and more particularly pointed out in the claims. v

In the accompanyingV drawings, wherein like reference characters indicate like or corresponding parts, Figure 1 is a side elevation of my im roved pulley with parts broken away to s ow the construction. Fig. 2 is a diametrical section substantially in line 2 2 of Fig. 1. Fig. 3 is a similar section of a slightly-modified form. Fig. `4 is a partial transverse section of a pulley-rim employed in my invention. Fig. 5 is a similar section of the preferred form of pulley-rim. Figs. 6

and 7 are similar sections showing slight modifications. Fig. 8 is a similar section of the form of pulley-rim shown in Fig. 5 with the pulley arms or spokes secured thereto. Fig. 9 is a partial section 0f the same on line 9 9 of Fig. 8. Figs. 10 and 11 are partial transverse sections showing the form of rim illustrated in Fig. 7 with slight modifications in the'pulley-arms. Fig. 12 is a partial section on line 12 12 of Fig.v 11. Fig. V13 is a partial transverse section of a pulleyerim with the arm in place, and Fig. 14 is a partial section on line 14 14 of Fig. 13.

As shown in the drawings, 1 represents the metal rim of a pulley, with its edges fianged inward at an angle to the face, as at 2 2, materially stiffening and strengthening the rim and aording means for connection with the ends 3 ofthe spokes 4. In the preferred form (shown in Figs. 1, 2, 8, and 9) the margins of the fianges 2 are turned inward, as at 5 5, Fig. 5, and notched, as at 6, for the reception of the ends ofthe arms 4, which are snugly seated therein, and thus conned against edgewise movement by the walls 7 7 of the notches, Fig. 6. The outer ends 3 of the arms 4 are formed'to suitably seat upon the inner side of the fianges 2 and are secured thereto in any preferred manner. As shown, rivets 8 8 or equivalent means serve to connect the parts. If desired, the extreme end of the arm 4 may be inwardly bent, as at 9, and firmly seated against the under face of the pulley, as shown in Figs. 8, 9, 11, 12, and 13. This construction also serves to strengthen the pulley and tends to relieve the rivets 8 of a part ofthe strain to which they are naturally subjected.

The extent to which the margins 5 of the fianges are employed may be varied as desired. As shown in Fig. 4, such margins and the accompanying notches 6 are dispensed with, the arms being secured to the flanges without other provision for a rigid edgewise connection. As shown in Figs. 2, 3, 8, and 9, the flanges 2 are extended at substantially a right angle to the face of the pulley and the margins 5 turned in at substantially the same angle to the flanges. As shown in Fig. 6, the flanges 2 are extended at an acute angle to the face of the pulley, the notches being formed in the fianges. ,The arms may be provided with T ends to seat against the flanges. In Figs. 7,10, 11, and 12 the marginal extensions are folded back upon the flanges, as at 10, thus providing for the retaining-notches 6 and side walls 7. As shown in Figs. 13 and 14, the flanges are slit near the arms, as at 19, andthe corners 20 turned over the arms, forming effective means for confining the armagainst edgewise movement and also additional means for binding the arms and flanges together.

The hub of the pulley may be of any suitable construction and arrangement and the pulley either solid or separable, as desired. As shown in the drawings, a separable or .split pulley is indicated, Figs. 1, 2, 3. As

shown, the hub comprises the separable castings 1 1 11, upon which the outturned ends l2 12 of the arms 4 are seated and secured. Rings 13 13 are positioned upon the ends 12 12 of the arms and the outer end of the hubs and preferably secured thereto by rivets `14 or equivalent means for the pur ose. Clamp-bolts 14at 14a serve to firmly bin the parts together upon the shaft or upon interposed bushings. Any preferred means may be employed to suitably engage the contiguous ends of the rim-sections. As shown,

IOO

IIO

lugs 15 15 are secured upon the rim near the intersection thereof, and clamping-bolts 16 serve to firmly bind the lugs, and thus the rim-sections together.

In the preferred form the arms for each half of the pulley comprise two parts, each part consisting of the arms for one side or edge of the pulley, which are connected at the hub by an integral web which, as designated, is the outturned part 12. The arms converge both radially and laterally from the rim toward the hub, Figs. 1 and 2. In the form shown in Fig. 3 the arms for each'pulley half are formed from an integral piece` of sheet metal, and the two parts or sets of arms for each half are connected by a web 17, the arms being folded back upon the web to form the extension 18 for the rings 13 13.
